LEATHER-DBESSIN G MACHINE.

Patented Sept. 25, 1917.

Application filed November 17, 1916. Serial No. 131,881.

To all whom it may concern:

Be it known that I, OTTo F. F EIX, a citi-- zen of the United States, residing at Gloversville, in the county of Fulton and State of New York, have invented a new and useful Leather-Dressing Machine, of which the following is a specification.

This invention has reference to leather the abrading roller.

In accordance with the present invention there is provided an abrading roller as before, but instead of a presser plate the abrading roller has associated therewith a presser roller. which may be rubber covered, and

associated with the presser roller are guiderollers constituting idlers and constrained sufficient-1y toward the presser roller to be actuated by pressure exerted on them through the leather or skin traveling between the presser roller and the guide rollers.

In the prior application the feed rollers are driven directly by gearing interposed between the guide rollers and the abrading roller, the latter being driven by power from any suitable source.

In the structure of the the means for transmitting'power from the abrading roller is much simplified instructure and also rendered more flexible by the employment of sprockets and chains, with only so much gear ng as is necessary to insure the proper direction of rotation andthe proper speed of rotatlon.

from a consideration of the following detailed description, taken in connection with the accompanying drawings forming part ofwthis specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any t ct onf rmity with present invention the showing of the drawings, but may be changed and modified so long as such changes and modifications come within the scope of the appended claims.

In the drawings Figure l is an end elevation of a machine embodying the invention.

Fig. 2 is a vertical front to rear section showing the rollers in end elevation.

Fig. 3 is a front elevation as viewed from the left hand side of Figs. 1 and 2, of the upper or roller containing portion of the machine.

Fig. 4 is a View similar to Fig. 3 but confined to the lower or treadle portion of the machine, with some parts in section.

Referring to the drawings there is shown a supporting frame 1 which'may be made of web and flange construction with the parts principally in the form of castings, but these are matters of detail construction and may be varied within wide limits. Furthermore, the frame construction needs no special de-' scription.

On top of the frame at opposite sides are guide portions 2 on which there is mounted a carriage having end members 3 capable of sliding lengthwise on the guides, and, carrying a top 4 constituting a table facilitating the handling of the skinswhile being treated. Each end 3 of the carriage is traversed by a stop screw 5 tapped therethrough and having a manipulating wheel 6 in' accessible; position so as to limit the extent of movement of the carriage in the direction and for a purpose which will hereinafter appear.

On each top member 2 is a rack bar 7 engaged by a pinion 8 on the correspond- I ing end of a rock shaft9 journaled in and extending through the sides 3 of the carriage. At appropriate points on the shaft 9 are secured offstanding arms 10, each connected at its outer or free end to a link 11 directed downwardly and having a pivotal connection 12 with a treadle 13 in turn piv- The, invention will be best understood otally mounted at 14 in appropriate portions of the frame 1. The treadle 13 has a footboard 15 in convenient position to be pressed upon-by the foot of the operator, while the other end of the treadle carries weights 16 in number and size sufficient to overbalance the foot board end of the treadle and to more c tain parts y the action of i y,-

Journaled in the side members 3 of the carriage is a shaft 17 carrying a roller 18, which latter, as appears from Fig. 2 of the drawings, is provided with a rubber surface or covering 19.

Mounted upon journal bearings 20 on the side members of the frame 1 is a shaft 21 carrying a carborundum roller 22. This roller may, as shown in the drawings, be provided with a surfacing 23 of carborundum or similar abrasive material, or it may be entirely of carborundum, these being matters which do not in themselves enter into the present invention. The roller 18 is so mounted on, the carriage that its rubber surface 19 may be brought into close relation to the abrading roller 22. The particular approach of the roller 18 which, as will hereinafter appear, constitutes a presser roller, to the abrading surface of the roller 22, is determined by the stop screws 5.

Power is applied to the shaft 21 through a pulley 24 by way of a belt 25 or in any other suitable manner.

Journaled in the frame 1 at a low point thereon is a shaft 26 carrying a gear pinion 27 and a sprocket Wheel 28. The pinion 27 and sprocket wheel 28 are in the particular showing of the drawings at respectively opposite ends of the shaft 26. Adjacent to the shaft 26 is another shaft 29 journaled in the frame 1, and this shaft carries at one end a gear wheel 30 meshing with the pinion 27 and at the other end carrying a sprocket pinion 31.

Mounted on the shaft 21 is a sprocket pinion 32 and mounted on the shaft 17 is a sprocket wheel 33.

Connecting the pinion 32 with the gear wheel 28 is a sprocket chain 34 and connecting the sprocket pinion 31 with the sprocket wheel 33 is a sprocket chain 35.

Power applied throu h the belt 25 causes a rotative movement 0 the abrading roller 22, and motion is transmitted from the shaft 21 of the roller 22 through the sprocket chain 34 to the shaft 26, and the latter transmits motion by way of the gears 27 and 30 to the shaft 29, which in turn transmits motion to the roller 18 by way of the sprocket pinion 31 and sprocket. wheel 33. The sprocket pinions and wheels and the gear pinion and gear wheel are so proportioned that a comparatively high speed of rotation may be imparted to the abrading roller, and at the same time the presser roller 18 may be rotated at a comparatively slow rate. As an example the abrading roller may rotate from eight hundred to a thousand revolutions per minute, while the presser roller has a peripheral speed of about fifteen feet per minute.

Associated with the presser roller 33 are other rollers 36, 37, respectively. These two rollers 36 and 37 have rubber coverings '01" envelops 38, and are carried by respective shafts 39 and 40. The roller 36 has its shaft 39 carried in bearing blocks 41 mounted to slide in guides 42 in one end of bracket arm 43 has a foot portion 44 provided with on opposite sides thereof. Each bracket arm 43 has a foot portion 44 provided with a longitudinal slot 45 traversed by screws or bolts 46 threaded into the corresponding portion of the frame 1, soas to support the bracket arm 43 in different positions of adjustment, the bracket arm being held fixedly in adjusted positions by tightening the screws 46.

The roller 37 carried by a shaft 40 is journaled at the ends. in bracket arms 48 having foot portions 49 with longitudinally extended slots 50 traversed by screws or bolts 51 entering the upper members of the frame 1, so that the rollers 37 may be adj usted and held fixedly in adjusted positions.

By means of spring mountings 52 a suitable elastic and yieldable pressure may be exerted upon the rollers.

The bracket arms43 and 48 are so adjusted that when the presser roller 18 is at its nearest approach to the abrading roller 22 the rollers 36 and 37 constituting guide rollers are so related to the presser roller as to permit the passage between the guide rollers and the presser roller of a skin to be treated and to hold the skin firmly-yet yieldably against the presser roller, while the latter in turn holds the skin against the abrading roller with desirable pressure.

The presser roller 18 isconnected up to the power receivin chine so as to be positively driven in contradistinction to being caused to rotate by the engagement of the skin therewith.

The normal tendency of the weights 16 is to cause the treadle 13 to rock the arms 10 in a direction'to rotate the pinions 8 in a manner to engage the racks 7 and propel the carriage so as to move'the-presser roller 18 toward the abrading roller, wherefore the presser roller will hold a skin against the abrad-ing roller with a pressure due to the weights 16.

The guide rollers 36 and 37 also engage the skin and hold it against the presser roller in a smooth, taut condition avoiding any tendency of the skin to wind upon the presser roller.

By the use of chain drive instead of the more complex transmission of the aforesaid application, not only is the construction correspondingly cheaper, but is smoother in running and far more flexible.

The use ofthe chain 35 for driving the presser roller 18 'is particularly advantageous since the roller 18 has a range of movement toward and from the abrading roller, which movement is easily permitted by the chain 35 without stopping the conelements of the maatinos stant rotation of the roller 18. llf toothed gearing were used for the purpose there would either be complete stoppage of the roller 18 when drawn away from the abrasive roller or the gear teeth would be so loosely connected as to be obtrusively noisy.

The roller 18 is covered with soft or medium hard rubber for certain work, while -tablished on the skins between the guide rollers and the presser roller. The pressure on the upper guide roller is further regulated by the spring pressure means de scribed.

On occasions the lower guide roller is not needed, and then it can easily be put out of commission by moving it out of the path of the presser roller.

In order to provide an adjustment between the arms 10 and the treadle 13 the links 11 may include turnbuckles 53.

As it is necessary to frequently clean the abrading roller, a dressing tool 54 is mounted on a feed rod 55 carried by bearings 56 on the frame 1 on that side of the abrading roller remote from the presser roller. The feed rod 55 may be actuated by a roller 57 which can be moved into and out of engagement with the abrading roller by an adjusting screw 58, or may be turned by hand.

In either instance the tool 54 is caused to travel along the abrading roller while the latter is rotating, and thus cleansing it from matter adhering to it and deposited upon the roller from the skins.

The guide rollers serve to hold the skin straight and prevent the formation of wrinkles.

ln doubling the action of the abrading roller, or when fieshing wet skins, the movement of the rubber presser roller should be reversed.

The dresser for the abrading roller to keep it true and clean may be a Huntington or Diamond dresser.
